  • Embodiments of the present invention provide a technical scheme for adjusting the size of a list item in a contact list of an IM client by utilizing multi-touch techniques.
  • a list item in a complex list control which includes various types of elements is adjusted through a multi-touch operation while it is ensured that the multi-touch operation does not conflict with existing dragging operations, scrolling operations and clicking operations to avoid incorrect operations, i.e., keeping the multi-touch operation compatible with existing operations of a touch control device without influence on existing operations and making the IM client much easier to use.
  • the list item may be adjusted at pre-set intervals, e.g. zoom in or zoom out a head portrait in the contact list smoothly and steplessly. While the size of the head portrait is adjusted, the display layout of all elements in the list item are also adjusted smoothly to make the user interface of the IM client highly functional and look neat, thus to improve service experience of users.
  • the method for adjusting the size of a list item may be applied to a client application running on a touch control device.
  • a zoom in/out operation corresponding to a multi-touch event may be implemented by two fingers or stylus pens placed on a touchscreen and moving away from or towards each other. As shown in FIG. 1 a and FIG. 1 b, two fingers or touch pens moving towards each other implements a zoom-out operation; and two fingers or touch pens moving away from each other implements a zoom-in operation.
  • the client application regards a touch by a finger or a stylus pen as a mouse event (e.g. a mouse button pressed, a mouse moving, a mouse button released and etc.) by default.
  • a zoom in/out operation corresponding to a multi-touch event may be confused with existing operations of dragging, scrolling and clicking, thus results in conflicting and incorrect operations. Therefore, the zoom in/out operation corresponding to a multi-touch event may be distinguished from other operations by a determination as to whether a touch event occurred is a multi-touch event.
  • all events are implemented through Windows messaging schemes, thus an embodiment of the present invention analyzes the operation of a touch event occurred on a message basis. Multi-touch events may be intercepted and analyzed separately with no mouse event messages sent to the client application. Events other than multi-touch events may be processed in system default manners, i.e. by sending a mouse event message to the client application.
  • FIG. 2 is a flowchart illustrating a method for adjusting the size of a list item according to an embodiment of the present invention. The method may include the following procedures.
  • a client device obtains a touch event.
  • the touch event may be obtained by a client system, and may be a finger press message or a stylus pen press message.
  • the client system judges whether the touch event obtained is a multi-touch event, performs procedures in block 204 in response to a determination that the touch event obtained is a multi-touch event, and performs procedures in block 203 in response to a determination that the touch event obtained is not a multi-touch event.
  • the client system may obtain the number of touch points of the touch event, and determines the touch event is not a multi-touch event if the number of touch points is one; determines the touch event is a multi-touch event if the number of touch points is larger than one.
  • the client system sends a mouse event message to the client application.
  • the client system records information of the positions where the multi-touch event occurs, and obtains one or more parameters of the multi-touch event based on the positions.
  • the client system may obtain and record information of positions where the multi-touch event occurs according to a pre-set period T, i.e. information of the movement of fingers or stylus pens, until the fingers or the stylus pens leave the screen.
  • the client system may obtain one or multiple parameters of the multi-touch event according to information of the positions recorded in each period.
  • the multi-touch event may be a two-touch event, and the parameters of the multi-touch event may include a center point and a zoom scale of a zoom in/out operation corresponding to a multi-touch event.
  • the client system may obtain information of initial positions of two touch points on the screen before the movement and information of final positions of the two touch points after the movement, take the position of the mid-point between the initial positions as the center point of the zoom in/out operation, and take the ratio of the distance between the two touch points after the movement to the distance between the two touch points before the movement as the zoom scale of the zoom in/out operation.
  • FIG. 3 is a schematic diagram illustrating information of positions of a multi-touch event corresponding to a zooming in operation.
  • Information of initial positions includes an initial position 1 of a first touch point and an initial position 2 of a second touch point with a distance of L 1 in between, a final position 3 of the first touch point and a final position 4 of the second touch point with a distance of L 2 in between.
  • the client system sends a multi-touch event to the client application together with the parameters.
  • the client application obtains the multi-touch event.
  • the client application adjusts the size of a head portrait control of a list item according to the parameters of the multi-touch event.
  • the client may adjust the size of the head portrait control according to the zoom scale obtained from the multi-touch event, and determine the position of the adjusted head portrait control according to the center point calculated. Since the client application may receive multi-touch events at pre-set intervals from the client system, the client application is able to adjust the size of the head portrait control, denoted by ImageControl, of the list item dynamically at pre-set intervals according to the parameters of the multi-touch events, and the adjusting may adopt the formulas below.
  • ImageControl.Height ImageControl.Height*Scale
  • ImageControl.Width ImageControl.Width*Scale
  • ImageControl.Height represents the height of the head portrait
  • ImageControl.Width represents the width of the head portrait.
  • the zoom scale each time calculated for adjusting the size of the head portrait control is also relatively small, thus resulting in stepless zoom of the head portrait control when the application is running.
  • the calculated sizes of the head portrait may be mapped to pre-set sizes, and the size of the head portrait is adjusted to a pre-set size which is closest to the size calculated.
  • the client application may also determine the position of the head portrait control after the adjustment based on the center point.
  • the client application adjusts the size of a contact panel control in the list item.
  • a list item may include other elements besides the head portrait control ImageControl, such as a contact ID, a nickname and a signature, and so on.
